**What is DNA replication? Write a good definition of this.** __DNA replication__ is the process by which a double stranded DNA molecule is copied to make two identical DNA molecules. Each DNA molecule is made up of two strands of DNA that are bound together by hydrogen bonds. During the replication process, the two strands of DNA that make up the double helix are split, producing two identical copies.

Replication plays an important role as it produces exact copies of the genetic material that can be passed on to the next generation of cells. It allows to copy the coded instructions for these characteristics and pass them from one organism to its offspring. Exact replication of DNA is important as DNA carries the genetic information for the cell. It must be carried out with great accuracy, since a change can be harmful to the organism.


 * Complete the following: **

Step 1: The two strands of the DNA separate. Each strand acts as a 'template' for making another strand which requires a supply of nucleotides. Step 2: The base paring rule is applied where A and T nucleotides always pair with one another, and C and G nucleotides always pair with one another because of their molecular structures.  Step 3: The DNA has been replicated and one ends up with two cells that are identical to one another and are also, identical to the original cell.
